Abstract (en)
[origin: EP1246022A2] By atomizing a siloxane and an organic titanium compound for flame combustion, spherical complex oxide fine particles of amorphous silica-titania are obtained having a particle size of 10-300 nm, a specific surface area of 20-100 m<2>/g, and a titania content of 1-99% by weight. By hydrophobizing the fine particles and adding them to a toner, a developer is obtained which is improved in fluidity, cleanability and uniform and stable charging.
